Oh, interesting! Nothing bad has ever come from a Car company buying a rail line, nope nothing at all
Anyways if you ever want to hate General Motors, read this Wikipedia article
Anyways what happened with General Motors is a great example of why Transit should be Publicly Owned because otherwise it can be bought up and service can be disrupted. Also Transit is a natural monopoly and should therefore not be placed in the hands of a private company, if want a reason why see what we currently have to deal with involving ISPs and Utilities Companies
